Good point about `ParenType`, but no, you cannot use
`R->getAs<FunctionType>()`, because that strips off all sugar, including
typedefs. However, I share your concern about hardcoding the forms of sugar.
Perhaps we should add `getAsAdjusted<T>()` like you were suggesting for
`TypeLoc` to `Type` as well?
